IMPROVEMENT IN RING SPINNING MACHINERY.

Specification forming part of Letters Patent No. l 80, 143, dated July 25, 1876; application filed September 4, 1874.

clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Similar letters of reference indicate corresponding parts.

Figure I is a vertical section through the center ofthe spindle. Fig. Il is an elevation of the spindle, showing the bobbin and ring in broken lilies. Fig. III shows the spindle Fig. IV shows the Fig. V Fig. VI

spindle-tube in section and elevation. shows the bolstertube and oil-cup.

' shows the oiling-tube in section and elevation.

Fig. VII is a perspective, showing the relation ofthe different parts` when the bobbin is partlyI raised.

This invention relates to the class of spinning machinery known as ring spinningframes,7 in which a traveler, passing freely around a ring, gives the required drag to the yarn while the same is receiving the necessary twist, and is also wound on the bobbin, the ring and its rail being a stationary part of the machine, so that the length of the thread' between the travelerl and the delivery-rolls shall always be a xed and unvarying quantity.

In the drawings, A is the ste-prall, B is the bolster-rail, and D the ring-rail, which latter is, in this invention, a stationary and xed The spindle revolves freely in its bearing in the bolstertube b, attached to the bolster-rail B, to which reciprocating motion is imparted, as was before usually done to the ring-rail. To allow this bolster-rail B, with all the spindles, to traverse with the least amount of power, I balance the weight of the same by means of the weights K, secured to chains or cords M, and passing over sheaves or pulleys, as is plainly shown in Figs. I and VII.

The spindle ais of uniform diameter, except the part below the whirl G, and has two narrow grooves on its sides, parallel with its y lslightly larger than the spindle, so that no friction may be caused at this upper part of the tube E. At the lower close-tting part of the tube E two splines enter and lit into the grooves of the spindle, so that when rotative motion is impart-ed to the spindle c, the same rotative motion is also imparted to the tube E, which latter has a reciprocating traverse motion imparted to it. The spindle a may, therefore, be considered as a non-reciprocatin g revolving or live spindle, while the tube E may be considered a reciprocating revoiving or live-spindle tube.

The spindle-tube E revolves and has its bearing within the bolster-tube b, on which it also rests, by. means of a collar projecting from the spindle-tube E, immediately above the bolster-tube,.and it is'prevented from lifting out of the bolster-tube by having the loose collar G secured to its lower end.

The bolster-tube is shown as extending to A of the bobbin.

The bolster-tube b is firmly secured to the block d, which forms the oil-cup, and also secures the whole upper part, or reciprocating part, of the spindle by the screw S. The oilcup is closed by a cap,`f, to prevent dust from entering the oil. This cap can be raised whe'n the spindle is running, and the machine may, therefore, be oiled without stopping` the same.

To insure a uniform lubrication of the bolster-tube, the wick-supporting tube O is inserted in the oil-cup. A portion ot' the wick surrounds the base of the'wick-tube O, and is always immersed in the oil. The ends of the wick extend upward to a groove formed on the upper edge of the tube O.- The oil is carried thus by the wick to this upper groove by capillary attraction, and uniformly su pplied to the bearing-surface.

The step-bearing i is provided .with a large oil-cup and closetting cover, h, so as to hold oil for a long time, and secure thorough lubri cation of the step.

The step-block is made of' a diameter larger than the diameter of the Whirl and cap, so that the spindle, Whirl, and cap may be removed through the opening made in the stepr-.Lil for the reception of the step-block z'. By this arrangement the spindle, Whirl, -and step may be all removed or replaced and firmly secured by the one screw S, securing the stepblock to the step-rail A.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, in a ring spinningfruine, provided with a stationary ring-rail, of the non -reciprocating live spindle with a reciprocating live-spindle tube, arranged to support the cop or bobbin, substantially as and for the purpose described.

2. The combination, in a ring spinningstep and step-rail, a reciprocating bolster-rail, a non-reciprocating live spindle, and a reciprocatin g live-spindle tube, the Whole operating together,y substantially as and for the purpose set forth.

In Witness whereof I have hereunto set my name.

THOMAS MAYOR.
